- Sun Nov 15, 2015 11:21 am #34070 Hi experts,

I am looking for some help as I am unable to build my firmware file(s) for the Blinky example.
When running the script as outlined in the esp8266-wiki/wiki/Building section, I get the following error: "implicit declaration of function".

Code: Select all(trusty)tiestvangool@localhost:~$ ./blinky.sh
Cloning into 'source-code-examples'...

I have started with clean Lubuntu VM on several machines and all result in the same issue.
Has anyone seen this before and/or guide me into a direction to get this resolved?

Thanks all,

Alternatively you can add -Wno-implicit-function-declaration to compiler options.
